Triangle Congruence: SAS

Construct a triangle with an angle of 70° between sides of lengths 4 and 7.
1. Select the SEGMENT WITH GIVEN LENGTH [icon]/images/ggb/toolbar/mode_segmentfixed.png[/icon] tool, and enter a length of 4.[br]2. With the SEGMENT WITH GIVEN LENGTH [icon]https://www.geogebra.org/images/ggb/toolbar/mode_segmentfixed.png[/icon] tool still selected, click on point A, and enter a length of 7.[br]3. Select the MOVE [icon]https://www.geogebra.org/images/ggb/toolbar/mode_move.png[/icon] tool, and drag point C so that you can see both segments.[br]4. Select the ANGLE [icon]/images/ggb/toolbar/mode_angle.png[/icon] tool. Click points B, A, and C to measure angle A. If the measurement is over 180°, undo and click on them in reverse order.[br]4. Select the MOVE [icon]/images/ggb/toolbar/mode_move.png[/icon] tool, and move point C until angle BAC has a measure of 70°.[br]5. Select the DISTANCE OR LENGTH [icon]/images/ggb/toolbar/mode_distance.png[/icon] tool, and then click on points C and B to measure the distance between them.[br]6. If you want to see your triangle more clearly, select the POLYGON [icon]/images/ggb/toolbar/mode_polygon.png[/icon] tool, and then click on A, B, C, and A again.[br]7. Answer the questions below the applet by constructing each triangle describe below.
Construct a triangle with an angle of 70° between sides of lengths 4 and 7. What are the measures of the other angle, side, and angle?
Construct a triangle with an angle of 130° between sides of lengths 2 and 5. What are the measures of the other angle, side, and angle?
